Here is a demo of my audio visualizer. The demo shows two audio visualization features implemented: (1) bass detection with a geometry shader to explode the mesh and (2) treble detection with a mesh deformation function. All camera moves and animations are based on the song "Fly" by San Holo that I used for this demo.
The program starts with a fly camera to the intro music and features a view of the entire scene/world, the bpm pulsing stars, and a galaxy sky box.
and I used hierarchical modelling for the pentagon cage that contains the bobbing sphere. I animated the wireframe and textured sphere to bob up and down together using a sine function and rotate separately on their own axes.
I used a geometry shader to explode the sphere mesh into separate triangular faces by passing in a uniform for the explode factor bassed on the bass detection algorithm data. I used frequency analysis on the low end of the spectrum to get frequency readings for the bass and detect bass in the song.
To create the mesh deformation visualization, I used a function that used spectrum data to modify the position buffer of the sphere mesh. The spectrum data that modified the vertex positions were read from the higher frequency portion of the spectrum to get treble data.
(default is bass explosion)
